A lication filed December 29, Serial No. 758733".

This invention relates to improvements in carpenters bevels and has as one of its objects to provide an instrun'ient of this class which iuay be readily a l' iistc(l ,to position its component parts at any desired angle with respect to each other a d the instru ment then employed in marking lumber such as rafters. sills, beams, etc, preparatory to cutting the same to the required dimensions.

Another object of the invention is to pro vide a carpentefis bevel which may he manu :t'actured at an exceptionally low cost and which will be substantial in its construction and, therefore, not liable to distortion or disarrangement of its component parts.

In the accompanying drawings:

Figure l is a view partly in plan and partly in section, 'ilh'istrating the instrument embodying the invention.

ligure 2 is a vertical sectional View taken sul'istantially on the line 2 2 of Figure 1, looking in the direction indicated by the arrows.

The bevel con'iprises a stock which is indicated by the numeral 1, and which may be made of wood or of metal, either as desired, and this stock is of oblong rectangular form and has parallel. side edges indicated by the numeral. 2 which are of right line extent and either of which may, therefore, constitute a straight edge. Near one end, the stock is formed with a slot 3 openingthrough its edges 2 and positioned midway between the planes oi the opposite faces of the stock.

The blade of the bevel is indicated by the numeral 4i and the same is of metal and has 'iarallel longitudinal straight edges indi* cated by the numeral ll? desired, one end of the blade may be cut at an angle as at 6, and the other end of the blade is formed with a slot 7 which extends longitudinally of the blade at the said end thereof and mi dway between and parallel to the straight edges The walls ol the slot 3 are formed with alined openings 8, and the shank of a set bolt 9 is fitted through 'the openings 8 and through the slot 7. a wing, nut 10 being threaded onto the bolt to bear against a washer '11. which is ii'iter 'iosed between the said wing nut and one face oi? the stock l. The head '12 of the bolt is located at the opposite face of the stock and a washer 13 is interposed between the said head of the bolt and the said face ol the stock. Whether the stock be formed of wood or of metal, the

his relu walls or,

less i'l til" nut 10 so as to draw the walls s. it toward each other and thus seenro i'richonally binding the opposite sides olade.

the slot 7, is indicated by the nuand the Slllil'le 18 at right angles to l and alerts one o the straight edges 5 of the b The bl, "le at the other straight edge "idcd with an offset or extension 15 atl'ori'l room for a scale 16, the mar. s rhich are impressed upon one face of the Made at its said end and upon the corre- SPOEE-Clll'lfZ :t'ace oil the extension 15. A similar scale 17 has its marks impressed upon the said Face of the blade alone; the straight eiil 'e which meets the edge 14; 'lhe scale are consecutively numbered, beginnine; from the corner ot' the blade formed by the edges 5 and 14, 'lrom O to 12, and the divisions oi each scale are re tn'esentative oi inches and fractions of inches, the actual linear length of each scale being, however, much less, of course, than the linear distance of? which it representative. The lateral extension l5 is pointed to admitoii the tool being: used in the capacity of the usual scratch cage, the marking point being dirccted by the stock 1 which functions as a guard.

It is the well lniown practice of carpenters to make use of an ordinary steel square in cutting}; lumber such, for example, as ratters, but even when an ordinary square is employed by skilled worlnnen, errors are liable to be made. the use of the present invention and by loosening the set nut 10, the user of the 'instruu'ient may adjust the blade 4; so as to bring; the proper scale marks the scales l6 and 17 into registration with the adjacent "r 'ght edge 2 ot the stock, thereby positioniiur the projecting length ol the blade at the proper angle to the other straight edge of the stool: to permit of the use of the instrun'ient in marking the lumber to be cut. it course, when the set nut lOis tightened. the blade l will be held securely in the position to which it has been adjusted,

as? i a";

lllfi and the instrument may then be employed by the carpenter in accurately marking the lumber to be cut.

Having thus described the invention, what We claim is:

A tool of the character described comprising a stock having one end portion formed with a slot closed at its ends and opening through opposite side edges of the stock, a blade having an end portion extendin transverselv through the slot of the stocl i and formed with a longitudinally extending slot, the said end portion of the blade having a side extension projecting transversely therefrom with one edge forming a continuation of the end edge of the blade, there being calibrations along the blade adjacent the side edge thereof opposite its side extension and other calibrations across the adjacent end of the blade and a portion of the side extension, and an adjustable fastener passing through the slots of the stock and blade and adapted to releasably secure the blade in an angularly adjusted position.

In testimony whereof We nflix our signatures.
